Post myocardial infarction:Treatment should be started between days 5 and after 21 after myocardial infarction,with an initial dose of 40mg four times a day for 2 or 3 days. In order to improve compliance the total daily doses three after be given as 80mg twice a day. Phaeochromocytoma (Used only with an alpha receptor blocking drug). Pre-operative: 60mg daily for three days. Non-operable malignant cases: 30mg daily.

In some instances a dosage of 640 mg may be required. The time needed for full hypertensive response to a given dosage is variable and may range from a few days to several weeks. Angina Pectoris Dosage Must Be Individualized. Starting with 80 mg propranolol hydrochloride extended-release capsules once daily, dosage should be gradually increased at three- to seven-day intervals until optimal response is obtained. Although individual patients may respond at any dosage level, the average optimal dosage appears to be 160 mg once daily. In angina pectoris, the value and safety of dosage exceeding 320 mg per day have not been established. If treatment is to be discontinued, reduce dosage gradually over a period of a few weeks.

Contraindication ::

Propranolol hydrochloride is contraindicated in 1) cardiogenic shock; 2) sinus bradycardia and greater than first-degree block; 3) bronchial asthma; 4) congestive heart failure (see WARNINGS), unless the failure is secondary to a tachyarrhythmia treatable with propranolol hydrochloride.

Drug Precautions ::

Propranolol should be used with caution in patients with impaired hepatic or renal function. Propranolol is not indicated for the treatment of hypertensive emergencies. Beta-adrenoreceptor blockade can cause reduction of intraocular pressure. Patients should be told that propranolol may interfere with the glaucoma screening test. Withdrawal may lead to a return of increased intraocular pressure. Risk of Anaphylactic Reaction While taking beta-blockers, patients with a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated challenge, either accidental, diagnostic, or therapeutic. Such patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction.

Drug Side Effects ::

Most adverse effects have been mild and transient and have rarely required the withdrawal of therapy. Cardiovascular: Bradycardia; congestive heart failure; intensification of AV block; hypotension; paresthesia of hands; thrombocytopenic purpura; arterial insufficiency, usually of the Raynaud type.
